Safely updating the Maestro SD card
Posted: Tue Jul 09, 2019 11:05 am
When updating the SD card contents, make sure you don't blow away your tuning. Tuning parameters are in the /sys/motion.g and /sys/thermal.g files, so make sure you don't overwrite those files! All other files in the /sys folder, as well as all files in the /gcodes, /macros, /menu, and /www folders, can be overwritten with newer versions. The /www contents are dependent upon the firmware loaded, so make sure you copy /sys/DuetMaestroFirmware.bin along with it.
